This study aims to analyze the level of mechanization in Niger while relying on the role played by animals used for farming in the regions of Maradi and Zinder (Niger Republic). Data collection was carried out between June and August 2020, using a questionnaire addressed to agriculture and related regional technical services and famers. The questionnaire helped to collect information on the evolution of mechanization, the different coupling tools, the areas worked with animal traction, the proportions of farmers using animal energy and the species of animals used for farming. The analysis of data collected showed that the farm park equipment has been strengthened by the purchase of agricultural equipments, especially for harness cultivation and intermediate motorization. The cart, the hoe, the plow and the seeder are the most harnessed tools to the draft animal. The percentage of use of these tools by producers are 87.5%, 42.5%, 41.67% and 11.67% respectively. The area worked using animal energy is about 16 times higher than that worked with human energy. It appears that about 90% of farmers use animal energy in carrying out their cropping calendar. Cattle are the most used (98.15%) for animal energy users followed by donkeys (1.85%) and camels (0.93%). Young animals (2-3 years old) are the most used (56.04%) on farming and traction with a pair of oxen is the most developed and represents 55.02% of the coupling. The maintenance of the coupling tools and their repairs are generally carried out locally by the users and other service providers. This confirms that the draft animal largely contributes to the development of agricultural mechanization in Niger.","PeriodicalId":7436,"journal":{"name":"American Journal of Applied Sciences","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83299749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the study is to automatically find rain time slots. The attenuation of the microwave signal, propagating between a transmitting antenna and a receiving one, due to the variations of the climatic conditions over the link, is a non-stationary signal. When a rain event occurs over a CML, the attenuation signal level increases proportionally to the rain amount. This level decreases again at the end of the rain. These abrupt variations are exploited here to detect rainy time slots. The proposed method consists in splitting the attenuation signal into frames and computing the variation of the energy between consecutive frames. To determine whether the current frame corresponds to a wet period, the proposed method, named Energy Variation (EVA), compares the variation of the energy with a given threshold, while taking into account the status of the previous frame. Simulation results from real attenuation data of the mobile phone operator Telecel Faso SA (Burkina Faso) show that the proposed method allows the detection of 84.61% of rainy events. The Matthews Correlation Coefficient (MCC) is higher than 0.9, which demonstrates that EVA can discriminate between wet and dry periods with high accuracy.","PeriodicalId":7436,"journal":{"name":"American Journal of Applied Sciences","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91275906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study, with the use of a methodological research tool called “Contemporary Narrative” attempts to analyze the contemporary problems resulting from the possible use of new technologies as weapons of mass destruction and more specifically, the strategic use of modern biological weapons as part of “Bio-Hybrid Threats”. The initial historical overview of the use of biological weapons is followed by an analysis of modern global technological-biotechnological developments within the context of global bioterrorism.","PeriodicalId":7436,"journal":{"name":"American Journal of Applied Sciences","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80768118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The new design proposed in this study uses the technique of Kodjo Attipou wood frames, but by interposing between the frames and the roofing tiles, a barrier is made of bituminous plywood. The barrier is composed of plywood 1.22 m in width, 2.44 m in length and 4 mm in thickness. The plywood is covered with a cloth of cotton fibers, impregnated in petroleum bitumen fluidized by kerosene. A test of permeability was conducted and has shown good results after 3 weeks of imbibition in water. The new composite material obtained can then serve as intermediate support in the system of roof coverings with roofing tiles and wood frames.","PeriodicalId":7436,"journal":{"name":"American Journal of Applied Sciences","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81403853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
